C1.3 Photosynthesis Flashcards
Plants use the energy of sunlight to make organic molecules from water and CO2, which makes them…
photoautotrophs
Heterotroph
A non-photosynthetic or chemosynthetic organism that obtains its food from other organism
What supplies most of the chemical energy needed for life processes in ecosystems?
The energy transformation of light to chemical
Equation of photosynthesis
6H2O + 6CO2 = C6H12O6 + 6O2
A waste product of photosynthesis
Oxygen, diffused through the stomata (pores)
Photosynthesis and electromagnetic spectrum
Photosynthesis happens within the visible range of the spectrum (including light) -> pigments are chemical molecules that absorb light (red and blue absorbed most effectively, green reflected) -> plant pigments can be extracted
